4To all whom t may concern:

Be it known that I, ARTHUR C. NoTHsTiNE, a citizen of the United States,residing at v Pittsburgh, in the countyof Allegheny and State ofPennsylvania, have invented cer`4 tain new and usefulImprovements' inBottle Caps and Stoppers, of-y which the following is a specification. Y

The present invention relates to aV combined stopper and cap, which isparticularly designed and adapted for use in connection n v withlaboratory reagent bottles".

Fig. l.

A further objecty is to combine a stopper with a bottle cap, in such yamanner as'to yproduce an article especially yadapted for reagentbottles, irrespective of the ysizeof ythe bottles. f The accompanyingdrawings illustrate.

Referring more particularly to the Y ings, the bottle l is provided witha4 suitable neck 2 to which is ground a'glass stopper 3 in the usualmanner. This stopper is provided with a cap 4, which as illustrated maybe approximately hemispherical, although if so desired anyy other formmay 'be adopted.

In Fig. 2. thevcap 4 is shownfasf/being. i

circular in cross-section, although obviously being circular. ,Itwill benoted that the height of the cap 4 yis somewhat greater than the heightof the stopper 3, so that the stopper and cap, after being removed fromthe bottle, maybe directly laid upon the f ter, for the reason that itis always desir-y bench or work table in the laboratory with- .outdanger of contaminating the stopper, or

the liquid to be held in the bottle 1. The

cap 4c obviously rprevents dust `and fumes from' settling upon thepouring lipV 5, which f is a disadvantagein bottles of this rcharacableto add the material from the bottle 1 ySpecification of Letters Patent.

,to the material being treated or i. tested,

without adding any impurities.y

' I call attention to the fact that caps have heretofore been placedupon reagent bottles of `this character, an ordinary hemispherical capor cylindrical cap being frequently open to the objection that two stepsare necessary forthe opening of the bottle, namely the removal of thecap, and thereafter the removal of the stopper, while in accordance withmy invention, the cap andstopper will be removed'in a single operation.Moreover, f asabove` stated, by makingfthe cap longerv than the stopper,I can avoid contaminating the liquid in the bottle 1.

-Heretofore it has beennecessary to handle kthe stopper itself, 'bymeans of which small This, however, is

quantities ofthe liquid withinthe bottle are t apt tocome in Contactwith the fingers of the operator, thereby producing discoloravtions orsores, whichV isk also avoided by means of the combined bottle cap andstop per forming my invention. It will be noted n that the lower edge ofthe hemisphercal capt, is some distance away from the bottle l, so'thatwhen the Vstopper sticks in the bottle,l as Stoppers in reagent bottlesyfre- Y quently do, the lower edge of the cap may be tapped lightly, inorder kto loosen the stopper. 'y Y f What I claim is :e The combinationwith a glass reagent bottle having a pouring lip, of a glass stopperground tofthe neck offsaid bottle, and a' cap 'integral with saidstopper, said cap being of greater height than said stopper, thev lowerend of ysaid cap being entirely free;

from Contact with the outer surface of said bottle, andfspaced therefroma considerable f' l extent, substantially as, and for the purposesdescribed. Y In testimony whereof I have affixed my signature inpresencey of two witnesses."
